PowerPoint presentations lock up the PC when you start the presentation. The PC is locked, tight, only a reboot works to get the computer back into operation. The computer is a PenIII/600MHz with 256MB ram (85 available resources when PowerPoint is loaded). Software is Win97 RS-2 and Office 97. This is consistent on 10 machines - we have removed and reloaded Office. Any suggestions would be appreciated. Ken Kenneth Kleinman Essex Town School District 802-878-8168 ext 107 [log in to unmask]
